10 meter 4000 W High Power Band Pass Filter

High power 10 meter 28 – 29 MHz band pass filters for BIG GUNS.

Bandpass filter is perfect for multi-station environments like special events, field days, and portable operating to protect receivers from excessively strong out-of-band signals. Our 10-meter filter is designed to have an extremely low loss from 28 – 29 MHz (10-meter band) and it is just 0.15 dB! Out-of-band interference is extremely suppressed. The filter is ideal to be on both reception and transmission. The 10-meter bandpass filter is declared at 4000 W, but the filter is designed for more power than presented. The Bandpass filter is placed in a powder-coated aluminum box. Silver-plated SO239 connectors and excellent filter design enable extremely low losses through 10 10-meter bands and high attenuation of out-of-band signals.   10 meter 4 kW Band-Pass Filter 28 – 29 MHz appearance.
